What is progesterone? How is progesterone controlled? What happens if I have too much progesterone? What happens if I have too little progesterone? Last reviewed: Jul Prev. Related Glands. In a normal menstrual cycle in which you don't become pregnant, the buildup and shedding of the lining of your uterus are controlled by a balance between estrogen and progesterone. If you have a condition where you are not ovulating but have excess estrogen—which is the case in polycystic ovary syndrome PCOS and occasionally in obesity —your healthcare provider may suggest the use of a progestin to help protect the lining of your uterus and to treat any abnormal uterine bleeding that may result.
Progestins are also typically used in many hormone replacement options for the management of menopause symptoms. When you are in menopause, the majority of the unpleasant symptoms, such as hot flashes, are caused by a lack of estrogen. Taking an estrogen replacement alone will effectively treat these symptoms and protect your bones. However, if you still have your uterus, you may need to also use a progestin or progesterone supplement to prevent abnormal growth of your endometrium or reduce the risk of endometrial cancer.
Progesterone can be supplemented if levels are too low or to help manage conditions where its counterpart estrogen is too high. It can also be used to either prevent or help sustain a pregnancy and is sometimes used in hormone replacement therapy during menopause.
Forms include pills, shots, vaginal gels, and suppositories. Progesterone is a sex hormone that plays crucial roles in the menstrual cycle and all stages of pregnancy. It also plays a role in breast development and preparing for breastfeeding. In males, progesterone produced by the adrenal glands and testes plays a role in making testosterone.
Progesterone can be supplemented if levels are too low or to support a pregnancy if there are certain risks, such as a history of preterm birth. Progestins, which act similar to progesterone, are commonly used in hormonal contraceptives and hormone replacement therapy during menopause. It is important to understand the many roles progesterone plays in the body and how it may affect your moods and energy levels in many different ways.
If you have any concerns about your hormone levels, discuss it with your healthcare provider. You can have your progesterone levels checked and explore your options. Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life.

Progesterone helps the uterus thicken in anticipation of receiving a fertilized egg. Irregular or absent periods may indicate poorly functioning ovaries and low progesterone. If you get pregnant, you still need progesterone to maintain your uterus until your baby is born. Your body will produce this increase in progesterone, which causes some of the symptoms of pregnancy, including breast tenderness and nausea.
If your progesterone levels are too low, your uterus may not be able to carry the baby to term. Low progesterone may indicate ectopic pregnancy. This can result in miscarriage or fetal death. Without progesterone to complement it, estrogen may become the dominant hormone. This may cause symptoms including:. A progesterone test PGSN can help your doctor tell if your progesterone levels are too low. The PGSN test can be used to monitor hormone replacement therapy or the health of a high-risk pregnancy.
Progesterone levels are usually higher than normal during pregnancy. Men, children, and postmenopausal women all have lower progesterone levels than women in their childbearing years. Progesterone levels fluctuate throughout the menstrual cycle.
They peak about seven days before your period. And levels can vary during a single day. Poorly functioning ovaries can cause poor progesterone production. You may not have any symptoms of low progesterone, and you may not need treatment.
Hormone therapy increases progesterone levels and may help thicken your uterine lining. This may improve your chances of a healthy pregnancy and carrying to term. Menstrual irregularities and abnormal bleeding can improve with hormone therapy. For severe symptoms of menopause, hormone therapy usually involves a combination of estrogen and progesterone. Women who take estrogen without progesterone are at increased risk of developing endometrial cancer.
